PIIPE GRIP.

Application filed August 9, 1921.v

To all whom it may concern: I

Be it known that we, THOMAS 'IV. BELL and THOMAS C. Rooms, citizens of the United States, residing at Sistersville, in the county of Tyler, State of West Virginia, have invented a new and useful Pipe Grip, of which the following is a specification.

his invention aims to provide a simple but eflicient means whereby an object may be rotated, the device being of peculiar utility in connection with threading together or threading apart, pipes of relatively large diameter, of the sort used in well drilling operations. I

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the drawings Figure 1 shows in plan, a device constructed in accordance with the invention; Figure 2 is a side elevation; Figure 3 is a. side elevation of the grip; Figure 4 is an end elevation of the grip; Figure 5 is a plan showing the flexible element.

In carrying out the invention there is provided a flexible element which may be a rope, the flexible element being provided at one end 50 with an enlargement or knot 1, and being supplied at its other end 51 with an outer loop 2. The intermediate portion of the flexible element is formed into a gripping loop S merging into a tightening loop 4 engaged about one end 5 of the gripping loop 3 in advance of the enlargement l.

The device embodies a grip 6 in the form of a block, of rectangular cross section ordinarily, and provided upon all four of its side surfaces with transverse sharpened ribs 7, one side of the grip being concaved, if desired, as shown at 8, the more readily to engage with a pipe 9 or other object which is to be rotated. The loop 3 passes through the grip 6, the grip having a tapered bore 10 for the reception of the loop 3, The loop Specification of Letters Patent.

3- ma ybe parceled with a wrapping or projection 11, forming an enlargement adapted to be wedged in the tapered bore 10, to hold the grip in place. A lever 12 extends through the loop 2.

In practical operation, the flexible element first is passed around the pipe or other object 9 to form the loop 3. Then, the flexible element is formed into the loop a, which is engaged around the end 5 of the loop 3 in advance of the knot or enlargement 1. The lever 12 is thrust through the loop 2 and bears at one end on the pipe 9. By means of the lever 12, the loop 3 may be made to grip the pipe 9, in conjunction with the part 6, the loop 4 constituting means for tightening the loop 3 and'the loop 2 receiving the lever 12, as aforesaid.

I claim 1. In a device of the class described, a provided at one end with an enlargement and supplied at its other end with an outer loop, the intermediate portion of the flexible element being formed into a gripping loop merging into a tightening loop engaged about one end of the gripping loop in advance of the enlargement; a grip through which the gripping loop passes; a projection on the gripping loop and wedged in the grip; and a lever extended through the outer loop.

2. In a device of the class described, a flexible element provided at one end with an enlargement and supplied at its other end with an outer loop, the intermediate portion of the flexible element being formed into a gripping loop merging into a tightening loop engaged about one end of the gripping loop in advance of the enlargement; a grip through which the gripping loop passes; and a lever extended through the outer loop.

3. In a device of the class described, a flexible element provided at one end with an enlargement and supplied at its other end with an outer loop, the intermediate portion of the flexible element being formed into a gripping loop merging into a tightening loop engaged about one end of the gripping loop in advance of the enlargement; and a lever extended through the outer loop.

4. In a device of the class described, a flexible element provided at one end with an enlargement, the intermediate portion of the flexible element being formed into a loop in advance of the enlargement; and a grip through which the gripping loop passes.

In testimony that We claim the foregoing as our own, We have hereto affixed our signatures in the presence of two Witnesses.
